I just purchased my first Short Term rental and am looking into Smart Home Devices.

If the remediation devices intrude significantly into the livable space, that will probably detract from value. 

Hello, We don't currently have a STR, but posting here because many STR use these kinds of devices.

As an active cyclist and triathlete, I am looking at places that are cycling and outdoor sports destinations to cater a rental to athletes.

I would think a detection device would be easy to fool or disable, and difficult to prove in court.I would focus on inspections and look for the following evidence, then document with pictures, written warnings, demands of cleaning/repairs, and follow-up inspections.
